Definitions

  • Some printing devices provide the convenience of having different types of printable media that can be automatically selected based on a desired printed output.
  • Such printers can have a media input tray system that includes multiple media trays to accommodate the different types and sizes of media.
  • a printer can have a main media tray to be loaded with plain paper, as well as a photo tray to be loaded with photo paper. The printer can then automatically engage either media tray in order to access the appropriate type of media depending on whether a user is printing a plain paper document or a photographs.
  • US 8 528 892 B2 disclosing the preamble of claim 1, which relates to a recording apparatus including a lower tray that stores recording media therein, an upper tray that stores recording media therein and capable of being mounted on the lower tray, and an edge guide which is disposed on the lower tray and has a guide surface along which the sheet edge is guided, wherein the edge guide is configured such that, when the upper tray is not mounted on the lower tray, the guide surface extends to a space for storing recording media in the upper tray; and
  • US 8 387 968 B2 which relates to a recording-material-feeding device including a stacking portion that holds a stack of recording materials, a lifting member that moves the stacking portion up and down between a feeding position at which a recording material is fed and a refilling position at which refill recording materials are supplied, a suction member that draws one or more recording materials by suction with a negative pressure, a negative-pressure-generating member that generates the negative pressure, and a stopping member that stops an edge of the stack of recording materials on the stacking portion and which includes a sealing member that maintains the level of the negative pressure, wherein the sealing member moves up and down between a retracted position at which refill recording materials are supplied and a sealing position at which the level of the negative pressure is maintained, the sealing member moving with the up-and-down movement of the stacking portion.
  • Printer manufacturers offer a wide variety of printing and/or imaging devices that bring a range of features to consumers. For example, many multifunction printers (MFPs), or all-in-ones (AlOs), can print, copy, scan and fax. Another feature often desired by consumers is a high quality photo print feature.
  • MFPs multifunction printers
  • AlOs all-in-ones
  • Another feature often desired by consumers is a high quality photo print feature.
  • generating high quality photo prints is generally not possible when printing on plain paper.
  • the use of plain paper for printing high quality photo images is impractical due to bleed-through of ink and/or other printing fluid, as well as other poor results related to the light weight and high porosity of the paper.
  • photo paper is coated in a way that reduces porosity and adds stability, resulting in less bleed-through and more surface ink that enables higher quality photo prints.
  • printers that produce high quality photo prints can utilize both plain paper to produce plain paper documents, as well as photo paper to produce high quality photo prints.
  • printers often include a media tray assembly that comprises two different media trays that are automatically accessible by the printer. The appropriate paper can be automatically picked by the printer based on print selections from the user. This type of media tray assembly relieves the user of having to feed photo paper into the printer or having to swap plain paper with photo paper using a single media tray when printing photos.
  • a media tray assembly for an imaging device such as a printer includes a main media tray for the plain paper and a photo tray for the photo paper. Both the main paper tray and the photo paper tray can have media width adjusters that enable differently sized paper to be used. The media width adjusters can be manually adjusted to align the paper within the tray so that pages of paper can be properly picked up and consumed by the printer.
  • Some media tray assemblies are designed so that the photo tray fits on top of and/or within the main paper tray. This nested arrangement of the two media trays reduces the amount of space taken up by both trays and enables a more efficient paper pick by the printer from the main paper tray and the photo paper tray.
  • the photo tray fits on top of or within the main plain paper tray.
  • the photo tray takes up room within the main paper tray that might otherwise be used to hold an additional amount of plain paper.
  • increasing the amount of plain paper held within the main paper tray can provide a significant benefit.
  • simply removing the photo tray to provide more room for plain paper in the main paper tray is not feasible.
  • the height of the walls of the media width adjusters in the main tray is limited to the point where the bottom of the photo tray rests within the main paper tray. Therefore, removing the photo tray and stacking additional plain paper into the main paper tray can cause paper toward the top of the plain paper stack to be higher than the walls of the media width adjusters. Paper stacked higher than the height of the walls of the media width adjusters will not be properly aligned when the user manually adjusts the media width adjusters. Because printers generally pick paper from the top of the media stack, the misaligned pages will likely cause a paper jam or other problem when picked by the printer.
  • examples of a media tray assembly for use in a printing/imaging system as described herein offer a versatile dual tray solution that enables increasing the amount of media (e.g., plain paper) available from a first media tray while maintaining proper media alignment for the printer.
  • the example media tray assembly also maintains the benefit of having dual nested media trays from which the printer can automatically access first media such as plain paper from within the first media tray or second media such as photo paper from a second media tray. It is noted that while examples herein are discussed with respect to the use of plain paper media in a first media tray and photo paper media in a second tray, other types of media without limitation are possible and contemplated for use within the first media tray and the second media tray.
  • the second media tray might also be referred to as a specialty media tray.
  • Examples of various types of printable media that may be suitable for use in the first media tray and the second media tray include plain paper, photo paper, card stock, transparencies, Mylar, polyester, fabric, canvas, plywood, foam board, and so on.
  • Examples of a media tray assembly include a first media tray for first media such as plain paper and a second media tray (or specialty tray) for second media such as photo paper.
  • first media tray for first media such as plain paper
  • second media tray for second media such as photo paper.
  • the second media tray sits in a nested position within the first media tray, and the printer can access media from either tray.
  • the second media tray is removed from the first media tray and the printer can access an increased amount of media from the first media tray.
  • the first media tray includes media width adjusters with walls that push paper into alignment as a user positions the adjusters.
  • the media width adjusters have a bottom portion and a top portion that are movable horizontally (i.e., from left to right) to accommodate different widths of paper.
  • the top portion of the media width adjusters is also movable in a vertical direction to increase the height of the walls when the second media tray is removed from the first media tray.
  • the heightened walls of the media width adjusters allow additional amounts of media such as plain paper to be added into the first media tray when the second media tray is removed.
  • each media width adjuster is drivable between first and second stable positions by a tension spring and a uniform motion mechanism that elevates and lowers the top portion evenly between the stable positions.
  • a tension spring and a uniform motion mechanism that elevates and lowers the top portion evenly between the stable positions.
  • a pin engages and translates a linkage assembly. Translation of the linkage assembly rotates a shaft with a cam that engages and activates the uniform motion mechanism.
  • a media tray assembly for use in an imaging device includes the features of claim 1.
  • a media tray assembly in another non-claimed example, includes a first media tray having two media width adjusters with walls to align media.
  • the media tray assembly also includes a second media tray positioned within the first media tray.
  • a wall heightening mechanism is used to increase the height of the walls upon removal of the second media tray from the first media tray.
  • a media tray assembly in another non-claimed example, includes a first media tray, and a second media tray insertable into and removable from the first media tray.
  • the media tray assembly also includes media width adjusters to align media within the first media tray.
  • the media width adjusters comprise height-extendable walls that extend upon removal of the second media tray from the first media tray.
  • FIG. 1 shows a top down view of an example media tray assembly 100 that includes a first media tray 102 and a second media tray 104.
  • FIG. 2 shows a top down view of the example media tray assembly of FIG. 1 with the first media tray 102 and the second media tray 104 separated from one another.
  • the second media tray 104 is in a position of being partially inserted or partially removed from the first media tray 102.
  • the second media tray 104 can be slidably inserted and removed from the first media tray 102 on rails 106.
  • the second media tray 104 can be removed by a user pulling the second media tray 104 out in a direction 108 from the first media tray 102 on rails 106, and it can be inserted by a user pushing the second media tray 104 in a direction 110 into the first media tray 102 on rails 106.
  • the first media tray 102 has left and right media width adjusters 112a and 112b, respectively, that can be manually repositioned from left to right in order to align paper within the tray 102.
  • the view of the media width adjusters 112 is mostly obstructed by the partially inserted second media tray 104 in FIG. 1 .
  • the length of the media width adjusters 112 extends along most of the length of the first media tray 102.
  • Movement of the left and right media width adjusters 112 is mirrored, such that when either the left 112a or right 112b media width adjuster is moved in an inward direction 114 toward the center of the tray 102 or an outward direction 116 toward the edge of the tray 102, the other media width adjuster 112 also moves inward 114 or outward 116 in a corresponding manner. This corresponding movement of the left and right media width adjusters serves to align paper in the center of the tray 102.
  • FIG. 3 shows a perspective view of a single media width adjuster 112 that is consistent with the left media width adjuster 112a shown in FIGs. 1 and 2 .
  • media width adjusters 112 have a top portion 118 and a bottom portion 120 that fit together to form a wall 122.
  • the wall 122 of a media width adjuster 112 comprises sections from both the top portion 118 and the bottom portion 120 of the media width adjuster 112.
  • the walls 122 of the media width adjusters 112 push against and align the media in the tray 102.
  • the wall 122 increases in height when the second media tray 104 is removed from the first media tray 102.
  • the top portion 118 of the media width adjusters 112 can move vertically (i.e., up 126 and down 124) to accommodate additional amounts of media within the first media tray 102 when the second media tray 104 is removed from the first media tray 102. More specifically, the top portion 118 of the media width adjusters 112 can move from a first stable position 124a ( FIG. 3 ) when the second media tray 104 is in the first media tray 102, to a second stable position 126a ( FIG. 4 ) when the second media tray 104 is removed from the first media tray 102.
  • the top portion 118 of the media width adjuster 112a shown in FIG. 3 is in a first stable position 124a. In this example, the first stable position 124a is when the top portion 118 of the media width adjuster 112a is down 124.
  • FIG. 4 shows a perspective view of a single media width adjuster 112a as in FIG. 3 , where the top portion 118 of the media width adjuster 112a is in a second stable position 126a.
  • the top portion 118 of the media width adjuster 112a is in the second stable position 126a when it is in the up 126 position.
  • the top portion 118 moves to the second stable position 126a when the second media tray 104 is removed from the first media tray 102, as discussed in greater detail below with reference to FIGs. 5-8 .
  • the top portions 118 of the media width adjusters 112 are up 126, there is additional room to stack media into the first media tray 102. As shown in FIG.
  • the sections of the wall 122 that are part of the top portion 118 are heightened or extended upward to accommodate for the height of the additional media that may be stacked into the tray 102.
  • the sections of the wall 122 that are part of the top portion 118 of the media width adjuster 112 move up 126 and down 124. Heightening the wall 122 in this manner ensures that the wall 122 can properly guide and align the additional amount of medai added within the tray 102 as the media width adjusters 112 are moved in an inward direction 114 toward the center of the tray 102 or an outward direction 116 toward the edge of the tray 102.
  • Components that function to raise and lower the top portion 118 of the media width adjusters 112 to heighten the walls 122 are discussed in greater detail below with regard to FIGs. 5 - 8 .
  • FIGs. 5 and 6 show different perspective views of the single media width adjuster 112a as shown in FIG. 3 , along with components of a wall heightening mechanism that operates to heighten the walls of the media width adjusters.
  • components of the wall heightening mechanism operate to raise and lower the top portion 118 of the media width adjuster 112 between a first stable position 124a and a second stable position 126a.
  • the bottom portion 120 of the media width adjuster 112 is shown as being partially transparent in order to better illustrate components of the wall heightening mechanism.
  • components of a wall heightening mechanism include a uniform motion mechanism 128 to elevate and lower the top portion 118 of the media width adjuster 112 evenly between the first stable position 124a and the second stable position 126a.
  • the uniform motion mechanism 128 comprises a four-bar linkage 128.
  • uniform motion mechanisms other than a four-bar linkage are possible and are contemplated herein.
  • Other uniform motion mechanisms can include, for example, a scissor lift mechanism.
  • the four-bar linkage 128 includes a coupler link 130 and two linkage arms 132 and 134, that are each rotatably coupled at a first axis 136 to the bottom portion 120, at a second axis 138 to the top portion 118, and at a third axis 140 to the coupler link 130.
  • the rotation of the linkage arms 132 and 134 around respective axes 136, 138, and 140 causes the other end of the coupler link 130 to move in the same way.
  • the four-bar linkage 128 provides a level motion upward and downward that elevates and lowers the top portion 118 of the media width adjuster 112 evenly between the first 124a and second 126a stable positions.
  • a cam 142 is another component of the wall heightening mechanism.
  • the cam 142 is rotatably and slidably coupled to a shaft 144 positioned on the underside of the first media tray 102 (see also FIGs 1 and 2 ).
  • the cam arm 143 engages the four-bar linkage 128 (i.e., uniform motion mechanism 128) and moves the four-bar linkage 128 up and down.
  • the cam 142 is rotatably affixed to the shaft 144 by the circumferential shape of the shaft 144. That is, the shape of the shaft 144 matches the shape of the center hole in the cam 142 about which the cam arm 143 is to rotate.
  • the shaft 144 has a cross shape 146 that fits into the corresponding cross shape of the center hole of the cam 142 to drive rotation of the cam 142.
  • other shapes for the shaft 144 are possible and are contemplated that may be equally as effective in driving rotation of the cam 142.
  • Other shaft shapes may include, for example, triangular, rectangular, star, square, hexagonal, double-square, triple-square, notched, and so on.
  • cam arm 143 As the cam arm 143 rotates upward, it contacts the uniform motion mechanism 128 and pushes it upward, which in turn elevates the top portion 118 of the media width adjuster 112 evenly from the first stable position 124a to the second stable position 126a.
  • Two cams 142 are slidably coupled to the shaft 144 so that they are able to slide along the shaft 144 as the media width adjusters 112 are moved in an inward direction 114 toward the center of the tray 102 or an outward direction 116 toward the edge of the tray 102.
  • Both media width adjusters 112 include a tension spring 148 coupled between the bottom portion 120 of the media width adjusters 112 and the coupler link 130 of the four-bar linkage 128 (i.e., the uniform motion mechanism 128).
  • the tension spring 148 applies tension to the uniform motion mechanism 128 to drive the top portion 118 of the media width adjuster 112 between first and second stable positions.
  • first stable position 124a i.e., down 124
  • the tension from the tension spring 148 exerts a force that tends to hold the top portion 118 in the first stable position 124a.
  • the cam arm 143 rotates to push the coupler link 130 of the four-bar linkage 128 (uniform motion mechanism 128) upward, the top portion 118 of the media width adjuster 112 travels in an arced path according to the rotation of the two linkage arms 132 and 134. As the top portion 118 travels past the mid-point of the arced path, the force from the tension spring 148 tends to pull the top portion 118 into the second stable position 126a (i.e., up 126).
  • FIGs. 7 and 8 show a side view of the example media tray assembly 100 from FIG. 1 , illustrating an example linkage assembly 150.
  • the linkage assembly 150 is another component of the wall heightening mechanism that operates to raise and lower the top portion 118 of the media width adjuster 112 between a first stable position 124a and a second stable position 126a.
  • the linkage assembly 150 includes a short first link 152 that is rotatably coupled at a first end to the cross-shaped shaft 144.
  • the first link 152 and the shaft 144 can be rotatably coupled in a manner similar to that of the cam 142 and the shaft 144 as discussed above.
  • the first link 152 receives the cross-shaped shaft 144 through a corresponding cross-shaped opening around which the link 152 can rotate.
  • the first link 152 rotates, it causes the cross-shaped shaft 144 to rotate.
  • a longer second link 154 is hinged 155 at one end to the second end of the first link 152. Movement of the second link 154 causes the first link 152 to rotate the shaft 144.
  • the second end of the second link 154 is confined within a slot 156 at the side of the first media tray 102 so that movement of the second link 154 is generally in a horizontal direction 158 with respect to the tray 102, as shown by the direction arrow 158.
  • the linkage assembly 150 is activated to rotate the shaft 144 when the second media tray 102 ( FIGs. 1 and 2 ) is removed from the first media tray 102. Referring to FIGs. 7 and 8 , as the second media tray 102 is removed, it engages a slidable pin 160, and the slidable pin 160 engages a hole within the second link 154 of the linkage assembly 150. As the second media tray 102 is being removed, it slides the pin 160 within a pin slot 162 and pulls the second link 154 toward the left as shown in FIGs. 7 and 8 . When the pin 160 drops down into a dog leg 164 along the pin slot 162, the pin 160 disengages from the second media tray 102 so the second media tray 102 can be removed.
  • the first link 152 of the linkage assembly 150 rotates, which in turn rotates the cross-shaped shaft 144.
  • rotation of the shaft 144 results in a corresponding rotation of the cam 142 and cam arm 143.
  • the cam arm 143 rotates upward, it contacts the uniform motion mechanism 128 and pushes it upward, which in turn elevates the top portion 118 of the media width adjuster 112 evenly from the first stable position 124a to the second stable position 126a. Elevation of the top portion 118 heightens the walls 122 of the media width adjuster 112, enabling additional paper to be stacked into the first media tray 102 in the absence of the second media tray 102.
